I've been using the computer for a month and a half more or less and everything went OK only few small problems but 2 days ago. It did not Boot.When starting the PC the following appeared:

Recovery
Your PC needs to be repaired

The boot configuration data file is missing some required information.
File:BCD
Error code: 0x000000d
You'll need to use the recovery tools on your.....

The first thing I did was creating a bootable USB with Windows 8 software, it did not work. SO i used Rufus, it worked and launched the Windows 8 installation and recovery but when I tried to recover, refresh, anything it told me the disk was locked... or anything the only thing I'm able to access is Command Prompt.

I've been trying some commands that I've seen online but no luck so far. Some commands tell me "OK, successfully something" But when reboot and I change to default the boot order and UEFI then the same error appears.

I booted in recovery mode but I can't make a system recovery drive on a USB because it says the boot files are missing. And I don't have a recovery disk because SAMSUNG ATIV 6 doesn't have a disc drive. I've been searching the web for a recovery disc download to no avail.

Unfortunatly I haven't made a backup or recovery file to boot my computer from so I'm stuck with the issue of finding a windows 8 iso file that matches my system, i tried getting the windows 8 iso from microsofts website but it asks for a product key before it lets you download the file, the problem is that my product key is built into the laptop and Toshiba has not provided me with the key on a sticker on the bottom or through any other method. apparently its built into the BIOS. i have a 16gb USB stick that i can boot from. using a key finder is obviously not an option because i cant start up the laptop. I was also wondering if i manage to find a windows 8 iso file to boot from, will my toshiba laptop automatically fill in the product key for windows 8 as i dont have it.

I got this msg tryng to refresh my pc . because my vaio gate app wasnt working right . so after the restar i just got the blue screen with this error the boot configutating data file dosent have valid infomation of an operating system.

Last night I set Acronis Disk Director to merge two partitions on my C drive. I had an unnallocated 100mb that used to be partitioned as system reserved, but I deleted that partition as it was not needed. So I made a new partition out of that unallocated space and set it to merge with my primary partition on my c drive. It restarted my computer and 40% through, showed an error and restarted quickly. Now I get the following message when attempting to boot my computer:

The second partition, that I attempted to merge, now has 1mb of space on it. Whenever I try to run chkdsk on the primary partition, it says that the disk structure is corrupt and unreadable. I need my c drive recovered.

I am having a problem with a new Dell Inspiron 15 3520 that came with Windows 8 installed and that I had been using for only a month when it went bad.

The problems started when I turned it off about ten days ago, and went I turned it back on a couple days later, and it was stuck in the apparently famous Windows 8 "Automatic repair couldn't repair your pc"/BSOD loop. I was not able to boot into safe mode. System restores made no difference. Somewhere along the line I found something that said that I had an "inaccessible_boot_device error".

From the repair menu maze, I was able to get to a command prompt. I used this to copy almost all of my files off of computer.

Chkdsk showed no bad sectors, no bad partition records, or other irregularities. sfc returned "Windows Resource Protection did not find any integrity violations". Some test (I do not remember which) showed that the boot record and BCD were fine. The Dell hardware diagnostic test showed everything working fine.

I am thinking that it is possible that the source of this was a virus or mechanical problem (I saw no evidence for either). If I had to guess, however, I would imagine that the computer stopped working after an automatic update pushed a corrupted/incompatible driver. I have seen discussions online about people having problems with NVIDIA video and/or SATA AHCI Controller drivers, and Windows 8 getting corrupted and stuck in the BSOD loop from that. At some point I saw a Windows Update Log (I am not sure where), that showed that, as Windows shut down the last time it was functional, automatic updates installed a new AHCI driver.

I tried downloading some new drivers for the 3520 from the Dell web site and installing them on the dead computer through a thumb drive and the command prompt. The downloads are all executables, however, and when I tried to run them, I get the message, "the subsystem needed to support the image type is not present". I believe that this message means that the driver executables are 32bit apps and won't run from a 64 bit command prompt. I also tried to use the "Drivers and Utilities" disk that came with my PC to do some driver rollbacks, but, I can't understand the file names or folder structure on the disk, and, when I try some to run some of the exe files ("setup.exe", for example) to get a gui interface, I get the "the subsystem needed to support the image type is not present" message.

After working on the problem for a while, I borrowed a friend's Windows 8 installation disk set. The computer will boot to the repair options off of the 64bit disk, but not the 32bit one. I did attempt a System Refresh off of the 64bit disk, and got back the message, "The drive where Windows in installed is locked. Unlock the drive and try again."

Around the time that I was messing with the BIOS settings to get the computer to boot off of the Windows 8 disk, I started getting a message "Your PC needs to be repaired - Boot Configuration Data file is missing some required information -- File:BCD -- error code 0xc0000034" at the start of my boot ups. I am not sure if I deleted a file somewhere during my repair efforts, or if I am getting this message because the computer is confused in efforts trying to boot off of the DVD. I get this message even with the DVD removed and the BIOS set to boot off of the Windows Boot Manager, however, so I am guessing that a file is now missing. And the message stops me from getting into the repair menus/command prompt any other way except through the installation disk.

Then I used bitlocker to encrypt it, and then for some reason when I tried to reboot the computer after doing the aforementioned, I get the message that windows cant boot, because the boot configuration is missing or conatins errors

I dont see how BitLocker and Disk Management can screw something up so much so that they either deleted or encrypted my boot config rendering me unable to boot up the computer.

What I did was shrinking the c:drive by 1000mb then formatted and partitioned those 1000 mb into a new drive. Secondly I encrypted the 1gig with Bitlocker with a short 12-character password.

I have an Aspire S3 laptop Windows 8 to 8.1 - that now has a BCD error blue screen upon start up that is error OXCOOOO0D - boot configuration data Recovery

Blue screen reads:

Your PC needs to be repaired.The BCD is missing some required info.File:BCDyou'll need to use recovery tools...

I don't have an install/repair cd/dvd, and I don't have my product key - since its on the BIOS and is unretrievable. I want to save ALL my files ... All I tried so far is to get into the BOOT by pressing F2 and switched it from UEFI to Legacy only it asks for BOOT disk...

I ended up managed to be able to boot into windows after i swapped out my motherboard and CPU to the new ones and everything seems to be working as it should, windows automatically installed the intel drivers and all my old programs and settings are there perfectly.

I can only boot into windows if i select my backup drive as #1 boot device in the BIOS, the SSD isnt even on the list.

The thing I don't understand lies in that, if i select my SSD as priority, where the directory of windows is installed, i get a bootmgr missing error - I've tried the various methods of recovering this using the cmd and a windows installation disc.

This isn't a huge issue but it's really tripping me out as to why this is occurring? I initially had some issues getting windows to boot so i installed a clean windows8 on this backup drive, i didnt change any settings at all. was only making sure that the SSD was being recognized and i hadn't corrupted it somehow. is it possible that the backup drive boot manager is directing it to the SSD.

I am planning on building a new computer, and I want to put a 250GB SSD (Samsung 840 EVO) in it to use with 8.1 Pro. However, most of the programs and data I need are still on the old computer's boot drive, specifically all of my STEAM games (none of which I have the DVDs for.)

My question is if I can create symlinks to the old boot drive without losing data on it. This will most likely be a temporary measure, as the drive's a fairly slow 5900RPM Barracuda, and I want something faster, but I can't afford a better one just yet...

I have a Dell 755 dual core, I loaded win 7 had a problem was with my CD rom, on boot up it was there, in devices it was there name and model, but as soon as I put CD in and opened the CD it would disappear off the machine sometime it would read what was on the disc and then disappear, I asked many question nobody gave me an answer. I installed it on a Dell 270 it works great.

Now on Win 8, the problem I have is if I have my mobile modem in the usb when I boot up my CD rom doesn't appear, if I take the modem out and boot up my CD rom is there with the drive letter G, when I put the modem in the CD remains and works correctly.

While I was messing around with my laptop, I decided to add on a fourth operating system, Arch Linux. I suppose I was pushing my luck a bit . Anyways, during the installation, I accidentally deleted the EFI system partition from my laptop, which contained the Windows Boot Manager and necessary files to boot. Great. I only made things worse by trying to troubleshoot, and broke grub as well.

I have a Windows 8 repair disk I made using the Windows 8 built in utility, but it does not boot: the computer turns on, and just hangs at the Toshiba splash screen.

I also can obviously not access the Toshiba recovery partitions, as they are booted into just like Windows itself.

I found a bootx64.efi file on one of my system's recovery partitions (Toshiba seems to have some really complex system going on) and placed it in EFIootootx64.efi. According to this site, FGA: The EFI boot process., I need to place the bkpbootmgfw.efi (on my system, that was what it was called, but I suspect boot-repair (ubuntu tool) messed something up when I was first setting up grub and the ESP and the bkp stands for backup) back onto the EFI System Partition.

Where to look for in the various Windows Imaging Format .wim and .swm files I have laying around my recovery partition(s) in order to extract the necessary EFI files. Any Windows Repair iso that works.

I've got a windows 8 laptop which gives me this error message when i try to switch it on:

"Your PC needs to be repaired The boot configuration data file is missing some required information.

File:BCD Error Code : 0xc000000d ............................" I'm sure you are all familiar with the rest of this dreaded error code.

I've tried all the repair options, recovery disks to a windows 8 bootable flash disk, the command prompt fix boot commands as well but still I get the same error message whenever i try to boot windows.

Now I'd like to know, can't i just copy the boot folders from another similar windows 8 pc and paste them into my harddrive to fix this?

Today, I restart my PC and now it refuses to load Windows. I have changed nothing recently, neither in BIOS nor software. It was a simple, routine restart and it hasn't worked since. I even tried re-imaging my primary drive from 1 month ago (after trying more recent images) and I still have the issue. In BIOS, all drives are recognized, bootable discs work fine. I tried resetting the BIOS just in case to no avail. Also tried disconnecting all USB devices, no good. I can't even get Linux to load, so I am suspecting my SSD might be shot--but it shows fine in BIOS. I don't mind replacing the drive, but I want to be more certain that is the issue before I spend the money. Or would this possibly be a motherboard issue?

I set myself up as System Administrator during installation. When I try to load the software from CD for a 5510 HP printer I get an error saying I cannot do it because I am not a System Administrator. I have verified that my profile show me with that designation.

I have looked around a bit and all solutions to this problem require me to get into the startup screen when booting from the installation disk upon startup. The problem is I cannot get to that screen!!

I am a uni student and can download windows 8 OS for free at msdnaa, I have done that and made an image file on a dvd and usb stick. I then put both of those into my dell N5010 (which is running win 7 now) and try to access them upon startup, (I go into the boot menu and try booting from booth DVD and USB) and both times I just get the error "boot manager is missing press ctr, alt, del to restart) so I cannot even get into the installation screen to do the repair that is says I need to do on all the other solutions I have seen.

I have brought a Dell Inspiron 17R SE. It came with a 1.5TB HDD With a rotating speed of 5400 RPM. As the day is passing the Laptop is becoming slow and slower. So I have thought to buy a Samsung 840 Pro 128GB SSD and install it along with my HDD. So my question is that is there any way to move all the files from my C: drive to that SSD and make that SSD as boot drive without losing all my files. Then my 1.5 TB HDD would be my data storing drive.

I had one sata drive wanted to add second sata as data drive.i disconnected older hard drive connected new one,installed windows 8 on it,everything went fine.I did not format older drive yet,reconnected it afterwards,changed boot order in BIOS but the second sata drive reads bus number 0,one with operating system reads bus number 1.Is this O.K.?Usually bus number 0 should be the operating system is on.How can I change this?

I want to move all my data from my MacBook to a laptop with Windows 8. I have everything backed up on an external HD; when I plug the HD into the laptop, it's not recognized. I've tried transferring via WiFi, but the MacBook is not allowing that to happen. Is there anything I can do with my backup HD so that it is recognized by my new Windows 8 laptop?

I bought an Asus g75vw with a preinstalled Win 8 because it was cheap, and afterinstalled an SSD to get some more OOMPH. But after a long time and lots of grief in trying to get the OS transferred to the SSD I managed to do so today due to theog and Paragon 12's clone-tools So I was happy as a clam up until a few mins ago when I discovered that the old 500 gb HDD was gone missing.

I had a working multiboot setup on my Acer Aspire One ZG5, running win xp, 7, 8.1, linux. I decided to add an extra partition, and in doing the resizing lost my Grub boot loader so can no longer boot into linux, but that's not important atm. I have also messed up my windows boot loader and at the moment I can only boot into win 8.1.

Win 8.1, 7 and legacy OS (xp) show in the boot menu but when I choose to boot into either xp or 7, I am presented with the messagewindows failed to start file: /ntldrstatus 0xc0000225

Previously I had the message filesystem unknown , missing NTLDR, but I ran the recovery console and that message no longer appears.

So I had this recovery error that said my winload.efi was missing so I ran the recovery from boot up and decided to recover. I read that this will delete the files from C: so I turned on the "Maintain User Data" option and selected all including the local disk c from advanced selection. But when the process was finished, my laptop was empty and no data was restored. What happened ? did I just misunderstand how it works and now it's gone ? or is it just somewhere I can't find ?

when I upgraded to Win 8.1 it was online. I have a win 8 disk but its not recognised. How can I reinstall win 8.1 and not lose anything as it reports missing files.

My daughter plugged in her ipad which normally opened in a setting which no longer works, instead opening in windows which it should not. I opened a file this morning and it opened in the wrong directory??

I got windows 8 online and I went to try and use the re install feature but its prompting me with this "Some files are missing. Your Windows installation or recovery media will provide these files" But since i got it online I don't have the CD but I do have the product key
